Spiced German Mustard
from Company’s Coming Christmas Gifts
"A medium hot mustard that’s perfect for bratwurst. Add heat by simmering longer to further reduce the volume and condense the flavour. Makes a great hostess gift."
½ c cold water
1/3 c yellow mustard seed
¼ c dry mustard
1 c apple cider vinegar
½ c finely chopped onion
2 T brown sugar, packed
2 cloves garlic, minced (or ½ tsp garlic powder)
1 tsp salt
½ tsp ground cinnamon
¼ tsp allspice
¼ tsp dill weed (optional)
¼ tsp dried tarragon leaves
1/8 tsp turmeric
1 T liquid honey (or less, to taste)
Combine cold water, mustard seed and dry mustard in medium bowl. Cover. Let stand for about 3 hours until mixture thickens to a paste.
Combine next 10 ingredients in medium saucepan. Bring to a boil on medium-high and immediately reduce heat to medium. Simmer, uncovered, for 10 to 15 minutes, stirring often, until reduced by half. Add to mustard mixture and stir.
Transfer to blender or food processor. Pulse with on/off motion until mustard is slightly thickened but grains are still visible. Pour into small heavy saucepan or top of double boiler. Heat on medium low or over simmering water for 10 to 15 minutes, stirring occasionally, until thickened. Remove from heat.
Add honey and stir well. Cool and transfer to a small bowl; cover. Chill for 3 days.
Spoon into sterile jar with tight fitting lid. Store in refrigerator for up to 2 years.
Makes about 1 cup.
